With the web the SEO practitioner can affect the inputs to the model and spend money to do so.
With the other examples I am not sure they can get an advantage by gaming it. In addition the pangrank models and how they weight it are more secret than Google. Google’s algorithm is secret but leaky (the search results are public)
I first heard about graph databases 13 months ago... there were so many questions in my head, I'm sure my colleagues still have PTSP when my name pops-up on Slack... :D
If you also have questions about one of the most used algorithms used in graph databases - PageRank - I've tried to give examples of usage in various use cases!
What have I missed? What other questions do you ask yourself about PageRank? What other graph algorithms do you have questions about?
